hi all

im trying to read SBUS signals from frsky R8 Pro receiver.
it defined OK, and i can read correct data using logic analyzer.

the thing is that the RX signal is inverted and i dont have any HW inverter on board.

can i invert the signal in software? i mean can i configure the channel to expect an inverted signal? 

or is it a way to use i/o monitor to invert the signal?

thanks.

Hi AssafREE,

I think it should be inverted by hardware.

Please refer to here.

it should. 

but it was last minute decision, so we try as always solve it by SW.
